Does urine always change to bright yellow with prenatal vitamins? it was and not it isn't as bright though i'm still taking them.

Bilirubin in urine: I wouldn't focus so much on the color of your urine. It is normal for urine to have a yellow tent it can be a light yellow to a dark amber depending on your hydration status. Yellow in your urine is bilirubin which is a breakdown product from the liver as it helps maintain equilibrium in your body. Your body is going through a lot of changes as you are pregnant, I would just focus at this time on taking your prenatal vitamins on time. If you develop urinary symptoms or fever or chills then discuss this with your doctor.

Prenatals: The shades of yellow can vary depending on the other components of your urine. no worries whether the coolor is there or not, continue taking your vitamins. :)
